Some will find this interesting but a bit of history...
An old cobber from Australia, friend of my father's who was on the Kokoda trail in ww2 told us the above and I've never forgotten about it.
He never spoke much about the war but he did tell few story's about fighting alongside the Gurkhas.
One story that he would tell often was being on duty at night near the enemy, you wouldn't hear a thing but suddenly an arm would warp around you and a hand clasped over your mouth, the arm around you would feel your shoulder for the amount of pips on the epaulette. Then a voice would say, "All good friend" then the gurkha would slip back into the night.
The reason for feeling the epallette was that they could tell by the feel if they were Allies or Japanese, that hand would also be holding the knife so if by any chance it was enemy they would slice the throat on the way back past....
